Compression test on ceramic.

There is a need to know accurately the strength of brittle materials in compression both to distinguish between competing statistical micromechanical theories of strength and to provide data necessary for engineering designs for the optimum use of these materials as load bearing elements. Any testing standard will do e g. Some materials such as a pet bottle distort during a compression test and are measured by the degree of distortion whereas other materials such as ceramics fracture produce a definitive compressive strength value. Compressive testing of ceramics 167 centration on extremely high compressive strength.

I would like to ask for help on the suitable compression testing standard for ceramics. Uniaxial compression is a well known experimental procedure to characterize the mechanical properties of metals polymers and ceramics by establishing the relationship between the uniaxial stress state prescribed by the loading condition and the induced triaxial strain state for an ideal uniaxial compression test a uniform stress state is expected to arise within the.
